解析对象：

public class News {public String resultCode;public String resultMsg;public ArrayList<MyData> resultData;public class MyData{ public ArrayList<MyList> course_list; public String cover_url; public String name; public String type_id;}public class MyList{ public String couse_id; public String img_url; public String students; public String teacher_id; public String teacher_name; public String title;}———————————————————————————————————–工具类：

public class StreamUtils {public static String StreamToStr(InputStream inputStream) throws IOException{ ByteArrayOutputStream outputStream = new ByteArrayOutputStream(); byte [] buffer =new byte[1024]; int len=0; while((len=inputStream.read(buffer))!=-1){ outputStream.write(buffer, 0, len); } return outputStream.toString();}public static News analyze(Context context) { // TODO Auto-generated method stub try { InputStream open = context.getAssets().open(“index.json”); String json = StreamUtils.StreamToStr(open); Gson gson = new Gson(); News news = gson.fromJson(json, News.class); return news; } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return null;}}———————————————————————————————————–————————适配器——————————
